Abstract
We describe a system for still image compression that uses several tra nsform sets in a multiple bases realization algorithm. Our algorithms reduce the number of encoded transform coefficients 20% beyond DCT-onl y compression. We extend these algorithms to use several newly develop ed LOT bases, resulting in useful algorithms for low bit rate (high co mpression) operation without blocking effect.
